The Temple of Nature; or, the Origin of Society: A Poem, with Philosophical Notes

by Erasmus Darwin

In the Latin language there are five cases besides the nominative, or original word, and in the Greek four. Whence the original noun substantive by change of its termination suggests a secondary idea either corresponding with the genitive, dative, accusative, vocative, or ablative cases, besides the secondary ideas of number and gender above mentioned. The ideas suggested by these changes of termination, which are termed cases, are explained in the grammars of these languages, and are expressed in ours by prepositions, which are called the signs of those cases.

Thus the word Domini, of the Lord, suggests beside the primary idea a secondary one of something appertaining to it, as templum domini, the temple of the Lord, or the Lord's temple; which in English is either effected by an addition of the letter s, with a comma before it, or by the preposition of. This genitive case is said to be expressed in the Hebrew language simply by the locality of the words in succession to each other; which must so far add to the conciseness of that language.

Thus the word Domino, in the dative case, to the Lord, suggests besides the primary idea a secondary one of something being added to the primary one; which is effected in English by the preposition to.

The accusative case, or Dominum, besides the primary idea implies something having acted upon the object of that primary idea; as felis edit murem, the cat eats the mouse. This is thus effected in the Greek and Latin by a change of termination of the noun acted upon, but is managed in a more concise way in our language by its situation in the sentence, as it follows the verb. Thus if the mouse in the above sentence was placed before the verb, and the cat after it, in English the sense would be inverted, but not so in Latin; this necessity of generally placing the accusative case after the verb is inconvenient in poetry; though it adds to the conciseness and simplicity of our language, as it saves the intervention of a preposition, or of a change of termination.

The vocative case of the Latin language, or Domine, besides the primary idea suggests a secondary one of appeal, or address; which in our language is either marked by its situation in the sentence, or by the preposition O preceding it. Whence this interjection O conveys the idea of appeal joined to the subsequent noun, and is therefore properly another noun, or name of an idea, preceding the principal one like other prepositions.

The ablative case in the Latin language, as Domino, suggests a secondary idea of something being deducted from or by the primary one. Which is perhaps more distinctly expressed by one of those prepositions in our language; which, as it suggests somewhat concerning the adjoined noun, is properly another noun, or name of an idea, preceding the principal one.

When to these variations of the termination of nouns in the singular number are added those equally numerous of the plural, and the great variety of these terminations correspondent to the three genders, it is evident that the prepositions of our own and other modern languages instead of the changes of termination add to the simplicity of these languages, and to the facility of acquiring them.

Hence in the Latin language, besides the original or primary idea suggested by each noun substantive, or name of an entire thing, there attends an additional idea of number, another of gender, and another suggested by each change of termination, which constitutes the cases; so that in this language four ideas are suggested at the same time by one word; as the primary idea, its gender, number, and case; the latter of which has also four or five varieties. These nouns therefore may properly be termed the abbreviation of sentences; as the conjunctions and prepositions are termed by Mr. Tooke the abbreviation of words; and if the latter are called the wings affixed to the feet of Hermes, the former may be called the wings affixed to his cap.

1. The third class of words consists of those, which in their simplest form suggest two ideas; one of them is an abstracted idea of the quality of an object, but not of the object itself; and the other is an abstracted idea of its appertaining to some other noun called a substantive, or a name of an entire thing.
